4 Claims, 3 Drawing Fig ures MOBILE VARIABLE HEAD, HEDGE TRIMMER Thisinvention relates to hedge trimming devices, and more particularly to avariable hedge trimmer.

It is therefore the primary purpose of this invention to provide a hedgetrimmer apparatus which will have a U-shaped member .to which is mountedadjustable members for raising and lowering the head portion containingthe shears.

Another object of this invention is to provide a hedge trimmingapparatus which will be powered so that it will be mobile as the shearstrim the hedges.

Another object of this invention is to provide a hedge trimmingapparatus which will have adjustment means for the head trimmer to bepositioned in a vertical position for trimming the sides of the hedgesas well as the top of the hedges.

A still further object of this invention is to provide a hedge trimmingapparatus which will have adjustable members carried upon the U-shapedmember that will have set screw means for securing the device at anydesired elevation.

Other objects of the present invention are to provide a variable head,hedge 1 trimmer which is simple in design, inexpensive to manufacture,rugged in construction, easy to use and efficient in operation.

These and other objects will'be readily evident upon a study of thefollowing specification and the accompanying drawing wherein:

FIG. 1 is a perspective view of hhe present invention showing oneposition of the trimmer head in phantom lines;

FIG. 2 is a fragmentary perspective view showing the trimmer head invertical position; and

FIG. 3 is a fragmentary perspective view showing a modified form ofpower unit on a base portion of the apparatus.

According to this invention, the hedge trimming apparatus is shown toinclude base portion 11 having wheels 12 and a power plant 13. Securedto base 1 1 is a suitable handle 14 for manipulating apparatus 10. A U-shaped tubular member 15 is fixedly secured to base 11 by means ofsuitable fasteners 16 and a V-shaped brace I7 is fixedly secured to base11 by means of suitable fasteners 18, the upper portion of brace 17being secured fixedly to a hook portion 19 which is fixedly secured tothe upper extremity of member 15 by means of a suitable fastener 20. Aslideable sleeve member'2l is carried on each side or arm of member 15and carried within the sleeve 21 is a tubular member 22 which is securedwithin the elevatable head 23 having the shears 24 for trimming hedges.A set screw 23' carried by head 23 provides a means of adjusting theangle of head 23 as shown in FIG. 2 of the drawings. A set screw 25carried by the sleeves 21, provides a means of rendering the head 23stationary at any desired elevation.

In use, the power plant 13 of base 1 1, provides power through the cable26 so as to operate the shears 24.

As will be seen in FIG. 3 of the drawing, a motor 13 maybe used to powerthe head 23 instead of the power plant 13 shown in FIG. 1 of thedrawing.

What I now claim is:

l. A mobile and variable height, hedge trimmer, comprising a basemember, wheels and handle means carried by said base member providingmobility therefore, a power plant carried by said base member aninverted U-shaped tubular member longitudinally means, means having oneportion secured to said sleeve means and having a spaced end portionadjustably supporting said trimmer head and drive means connectedbetween said power plant and said shear means.-

2. The combination according to claim 1, wherein said U-shaped member isfixedly secured to said base member by suitable fasteners at one side ofsaid base member and said brace is V-shaped in configuration and issecured by suitable fasteners to the opposite side of said base portionof said device and the upper portion of said brace member is fixedlysecured to a hook member engaging the upper extremity of said U-shapedmember, said hook member being secured by suitable fastener means tosaid upper portion of said U-shaped member.

3. The combination according to claim 2, wherein said sleeve members areslidable upon the arms of said U-shaped member and are rendered securethereto at any desired elevation by set screw members carried by eachsaid sleeve and said supporting means includes tubular members that aresecured within the head carrying the motor driven shears, said headhaving set screw means for adjusting the angle of said shears forvertical side cutting of hedges.

4. The combination according to claim 3,, wherein said drive meansincludes a flexible cable connected at one end to said power plant andat the other end to said shear means.
